Zero Liquid Discharge Systems Market Forecast: What Value Will The Market Reach By 2030?
The zero liquid discharge systems market has experienced significant growth in recent years. Forecasts indicate it will expand from $7.02 billion in 2025 to $7.63 billion in 2026, demonstrating a compound annual growth rate (CAGR) of 8.7%. Historically, this growth has been driven by factors such as industrial water pollution control, stringent regulatory discharge limits, the expansion of thermal power plants, increasing water scarcity concerns, and the growth in heavy industries.
The zero liquid discharge systems market size is anticipated to experience robust growth in the upcoming years. It is projected to expand to $10.6 billion by 2030, achieving a compound annual growth rate (CAGR) of 8.6%. This projected growth can be ascribed to several factors, including more stringent environmental regulations, escalating industrial water reuse requirements, the expansion of petrochemical projects, an increase in mining operations, and the adoption of circular water management strategies. Significant developments expected during this forecast period include a surge in industrial water recycling, broader implementation of hybrid ZLD system deployments, an increased reliance on membrane-based technologies, the integration of energy-efficient evaporation systems, and a strong focus on achieving total wastewater elimination.

Zero Liquid Discharge Systems Market Expansion Drivers: What’s Shaping Future Growth?
The expanding trend of urbanization is anticipated to fuel the expansion of the zero liquid discharge systems market in the future. Urbanization is defined as the large-scale relocation of people from countryside regions to city areas. This shift supports the need for zero liquid discharge systems because of growing requirements for energy and water. For example, a 2022 report from the World Bank, a US-based international organization, indicated that over 50% of the global populace resides in urban locales. Projections show that the urban population will reach 6 billion by 2045, marking a 1.5-fold increase. Furthermore, by 2030, urban built-up areas worldwide are expected to grow by 1.2 million km2, with urban land usage expanding up to 50% quicker than population growth. Consequently, the rise in urbanization is propelling the growth of the zero liquid discharge systems market.

Zero Liquid Discharge Systems Market Industry Trends Fueling Future Revenue Growth
Major companies within the zero liquid discharge systems market are concentrating on developing advanced, high-recovery treatment technologies, such as electrodialysis reversal solutions, which enhance water reuse, improve resource recovery, minimize fouling and maintenance, and support efficient operation under challenging industrial conditions. For instance, in October 2025, QUA, a US-based membrane technology company, introduced EDR-Q, an advanced electrodialysis reversal technology engineered for high-recovery desalination, water reuse, and specialized process applications. Expanding QUA’s membrane portfolio, EDR-Q assists industries like food and beverage, critical minerals, and wastewater treatment by enabling selective ion removal and effective resource recovery. This system utilizes automatic polarity reversal to limit fouling and scaling, facilitating up to 95% water recovery and reliable performance in conditions with high silica, sulfate, and turbidity. Featuring chemical-free in-situ cleaning, broad pH tolerance, and low-maintenance operation, EDR-Q provides a cost-efficient solution. It is available in three compact, modular models with flow rates from 1.5 to 9.0 m³/hr.
